ASH SIFCER FOR` FULELLWAGES.

s Application fllcdf lliarch 28, w22; Serra-1- No. M7365.-

`of l/viseonsin, have invented certain new and usefulimprovements in Ash Sitters for Furnaces; and l do hereby declare that the following is a full, clear, and exact description thereof.

rlhis invention pertains to attachments for `furnaces and more particularly toa device adapted to sift the ashes as they are shaken from the grate. i y

Theprimary object ofmy invention refsides in the provisionof means adapted `to be positioned within the ashpit of a furnace, whereby ashes shaken from the grate will be siftedand the unconsumed particle-s of fuel separated therefrom.

.A more specio object, incidental to the foregoing, resides in the provision of a normally inclined screen hinged within the ashi pit of a furnace for the purpose of sifting the ashes shaken from the grate,fthe same being adjustable to a substantially hori- Zontal position to permit convenient removal `of the ashes from the ashpit.

With the foregoing and other objects in view, the invention consists in what is herein shown and described and more particularly pointed out and defined by the appended claim, it being; understood that various modifications in the mechanical details of construction are contemplated as within the terms of the appended claim.

In the drawings i Figure l illustrates a sectional view i through a portion of a conventional type of furnace, showing the invention positioned therein, and v y Figure 2 is a sectional view taken on the line 2--2 of Figure 1A` y Referring?,- now more particularly `to the accompanying drawing, the numeral l design nates a conventional type of furnace consistingV of an outer casing; 2 and provided with a fuel compartment 3 and shaker grate 1l.

Below the fue] compartment 3 is the customary ashpit 5 for receiving4 the ashes shaken through the grate. While l have shown a specific structure of furnace for the purpose of illustrating the application ofthe invention, it will be readily appreciated that the same may be used in connection with furnaces of the hot water, hot air, or steam types.

adapted to be` positioned within the ashpit of the saine without necessitating` alteringof s the furnace.` For this purpose l provide a pair of side standards G connected by means of cross members 7. The side standards G are spaced apart approximately the width of the ashpit and are, therefore, positioned adjacent the sides of the pit, in which position they will in no way interfere with the removal of the ashes. Pivotally connected to the side standards 6,'at its upper end, is a normally inclined screen 8 adapted to be supported on the ground at its lower edge. The screen 8 is provided with upwardly extending sides 9 adapted to prevent large particles, which do not pass through the screen, from rolling;lr off to the side of the same.

While l have shown and described an inclined. screen as constructed from woven wire, it is obvious that the same might be formed of perforated sheet metal,`if so desired. y The free end of the inclined screen 8 is provided with means, preferably a loop 10,

for the'purpose of locking the screen in a substantially horizontal position parallel with the grate 4i. rllhis is accomplished by .passing the loop over a hook provided withthe larger, or unconsumed particles of fuel,

will be delivered to the front` of the ashpit where they may be readily removed. ln some instances, it may be desired to position the screen in its vertical position while shaking` down `the ashes, in which case the unconsumed particles of fuel will be retained upon the screen until such time as same is lowered to the inclined position. A. further purpose in adjusting the screen to a horizontal position is to permit convenient removal of the ashes, which are passed through the screen into the pit.

While l have shown the device as preferably constructed in the form of an attachment, itis obvious that in some instances l standards, a normally inclined screen pivoted at its upper end l etiveen the side standards and provided with upwardly extendingr sides, a furnace envelopingr said sci-eem a hook on said furnace, and a loop carried by the free end of said screen adapted to coopera te with said hook for iocking said screen in a suhstantiall;7 horizontal position. said loop heingreieasable to permit said screen t0 he swung to inclined position to separate large particles from the ashes and deliver them to the front ot' the ash pit.

ln testimonyv that I claim the 'foregoing l have hereunto set my hand at Racine, in the countyv of Racine and State of Tisconsin HERMAN V, VROOMAVN.
